AI and Blockchain: Stronger Together
Sriram Vishwanath
First, a little bit about me
Professor at UT Austin (16 years)
PhD Stanford, Engineering and
Statistics
MS Caltech, Engineering
Research in AI/ML: GANs, Causal
Leaning and Generalization/transfer
learning
Past year: building a new, scalable,
provably secure blockchain
Founder, BrilliantMD
AI, Blockchain and the Future
Not everything is predictable!
A careful approach to AI and Blockchain
Population àPersonalization
I can predict it all à AI based on measured precision
Use across all applications àTarge te d application of Blockchain
General Directions:
Only use Blockchain when absolutely necessary
Use AI for targeted applications, not as a general platform
Simpler ways of accomplishing the task in a majority of cases
Some cases clearly benefit from AI + Blockchain
Importance of a Good Methodology
Caution: Poor methodology causes Garbage in, Garbage out

AI/ML
Insights – Clinical, Operational
and Financial
Personalization of patient care
Business process improvement
Reduce waste, improve bottomline
Targeted interventions
Streamline and prioritize clinical
and non-clinical operations
Drive rapid informed decision
making
Blockchain
Secure multi-party transactions
Private Auditable Ledgers, HIPAA
compliance
Trustless consensus between
disparate players
Real-time resolution
Improved transparency into
datasets
Optional: Tokenization for
incentive design
AI/ML Architecture
Opensource tools: Scikit-learn,
Tensorflow
Well developed and maintained
Preprocessing essential
Normalization and outlier detection
Cleanup
Active learning and feedback
Essential to continuously improve the
model
Blockchain Architecture
Hybrid on and off chain
architectures
Scalability essential
Layer 1 and Layer 2 scalability
Security guarantees
Many chains use proofs that offer no
security guarantees
Privacy guarantees
HIPAAA compliance
AI + Blockchain: Benefits
Can transform black box AI to “glass box”. Improve interpretability and transparency of results

AI + Blockchain: Benefits
Blockchain enables improved targeting and personalization
AI + Blockchain: Benefits
Blockchain enables compliance through Private Auditable Ledgers (PALs)
AI + Blockchain: Benefits
Blockchain enables AI-based smart contracts to be executed in real-time

Example AI + Blockchain Applications
Business process efficiencies
Claims processing
Provider credentialing
Prior authorization processing
Supply chain transparency
Improved patient engagement
Addressing Clinical trial efficiencies
Clinical care improvement through patient empowerment and transparency
USE-CASE: CLAIMS
DENIAL MANAGEMENT
ISSUES WITH CURRENT PROCESS
Reactive
Manual process of rework
Lack of transparency, constantly changing rules
AI + Blockchain:
AI: Streamlines/ turbo charges existing process for claims submission by RCM team
AI: Enables staff to focus on high value/important claims, Predicts missing fields
Blockchain: Identifies and highlights missing items (documents and fields) prior to
submission
Blockchain: Enables tokenization to incentivize error-free submission/prior-
authorization
OVERVIEW: BENEFITS OF COMBINING THEM
IMPROVES CLAIM SUBMISSIONS THROUGH AI
reduces errors and predicts acceptance likelihood
REDUCES REWORK & DENIAL RATES
Increases revenue and reduces costs
FRICTIONLESS PROCESS
Blockchain enables instant traceability and
containers ensure simple integration
SECURE, SOLUTIONS
Private auditable ledger ensure HIPAA compliance
and provable security guarantees
CLOSE PARTNERSHIP WITH CARECENTRIX
Summary: AI + Blockchain, Stronger Together
Do you need a blockchain?
Centralized, fully trusted systems do not require a blockchain
Are you doing AI/ML Correctly?
Do you know the measured precision of your AI/ML tool?
For both: Is it essential for your success? A clear use-case?
If Yes, then:
AI + Blockchain: A match made in heaven
Blockchain improves AIs transparency
Blockchain enables greater personalization in AI
Blockchain powers AI-based smart contracts and DAO's (Decentralized Autonomous
Organizations)
Blockchain enables compliance through private auditable ledgers
